Lovely man, I was lucky enough to meet him a few times when Catching the Impossible was being filmed. On one day we managed to put him on a salmon which he hooked and landed from the Royalty when the cameras were rolling.
His wife died recently and I remember that it was reported that he was overcome with grief (it had been a long and happy marriage). I thought then that he may not be with us much longer, but 93 is a good innings.
He's been pretty much a constant all my life: from novelty songs and Jackanory as a child to Dr Who as an adult. What a career and what a legacy to leave.
